PI,芳名为“灌注指数”,全称为perfusion index,是经皮脉氧饱和度监测仪测得的,定义为局部组织的搏动性成分AC(主要为搏动性的小动脉)与非搏动性成分DC(静脉、毛细血管和非脉动动脉血及组织)在940nm处的光吸收比值,即AC940/DC940。 虽然同样是通过光学原理从Sp...

The perfusion index (PI) is the ratio of the pulsatile blood flow to the non-pulsatile or static blood in peripheral tissue. Perfusion Index thus represents a non-invasive measure of peripheral perfusion that can be continuously and non-invasively obtained from a pulse oximeter. As the ...
